Sending Push via Postman using Firebase Messaging

Question

I'm trying to use Postman to send a single Push Notification using Firebase Cloud Messaging service.

This is a working cURL command for the same purposal, on which I'm using as a reference.

curl -X POST --header "Authorization: key=<API_ACCESS_KEY>" --Header "Content-Type: application/json" https://fcm.googleapis.com/fcm/send -d "{\"to\":\"<YOUR_DEVICE_ID_TOKEN>\",\"notification\":{\"body\":\"Firebase\"} \"priority":\"10"}" 

What I have done so far..

1 - Set the Headers appropriately

2- At Body , I'm using raw

{     "to" : "<YOUR_DEVICE_ID_TOKEN>"     ,       "notification": {     "body": "Firebase Cloud Message"   }    } 

When executing, I'm getting back 401 - Unauthorized.

What's missing to correctly send the push notification?

Answer 1

The correct way to set up Authorization key at Header is

key=<API_ACCESS_KEY>

and not only

<API_ACCESS_KEY>

Silly mistake, but since this could be useful for someone for testing Firebase Messaging with Postman I'm leaving the question opened.

Answer 2

Posting FCM through POSTMAN

Body - to is token id (should be generated through instance token) write body in raw binary application/json

{    "to": "cpa8cZPjq-w:APA91bF122f1Rnhu9v47bL    YMajaNTHAIU5SzItDwTy9o2MCIveG0PlK78VPvp3d    CqjwnUKZ4    ngi1trSyM3_aXttW62iknFfbPGtjRLhZr6wq-3qFdboz8gzdOGPz**********",     "notification": {      "body": "Hello",     "title": "This is test message."    }    } 

header: should have authorization :server key

Content type : application/json after posting here the success message:
